Network Mapping tool

Wrote another little tool while I was preparing for an Exam. Its called Nwmap or Network Mapper. You just have to start up a sniffer and save your packet captures in a .pcap file. Feed this to nwmap and it'll give you a list of subnets that are being used internally. You can then sit and probe all of these manually.

You can download NWmap at http://sourceforge.net/projects/nwmap/.
